Outcomes of supraventricular tachycardia ablation: Results from the Singapore ablation and cardiac devices registry

BACKGROUND The Singapore Cardiac Databank was designed to monitor the performance and outcomes of catheter ablation. We investigated the outcomes of paroxysmal supraventricular tachycardia (PSVT)-ablation in a prospective, nationwide, cohort study. METHODS Atrioventricular nodal re-entrant tachycardia (AVNRT), atrioventricular re-entry tachycardia (AVRT) or atrial tachycardia (AT)-ablations in Singapore from 2010 to 2018 were studied. Outcomes include acute success, periprocedural-complications, post-operative pacing requirement, arrhythmic recurrence and one-year all-cause mortality. RESULTS Among 2,260 patients (mean age 45±18years, 50% female, 57% AVNRT, 37% AVRT, 6% AT), overall acute success rates of PSVT-ablation was 98.4% and increased in order of AT, AVRT and AVNRT (p
